These properties can be those of stress, intonation (a single pitch and rhythm contour), or tonal patterns. Prosodic units occur at a hierarchy of levels, from the syllable, the metrical foot and phonological word to the intonational unit (IU) and to a complete utterance. [1]
The limiting factor for telephony based speech recognition is the bandwidth at which speech can be transmitted. For example, a standard land-line telephone only has a bandwidth of 64 kbit/s at a sampling rate of 8 kHz and 8-bits per sample (8000 samples per second * 8-bits per sample = 64000 bit/s).
The Harvard sentences, or Harvard lines, [1] is a collection of 720 sample phrases, divided into lists of 10, used for standardized testing of Voice over IP, cellular, and other telephone systems. They are phonetically balanced sentences that use specific phonemes at the same frequency they appear in English.
Critics of the slurve call the pitch a sloppy slider because of its wide break. They claim that the slurve produces more home runs than a late-breaking slider. [1] The usefulness of the slurve is debated. The slurve is also claimed to cause problems to a pitcher. In 1998, Kerry Wood claimed his elbow soreness was caused by throwing the slurve. [3]
In more complex types of pitch-accent languages, although there is still only one accent per word, there is a systematic contrast of more than one pitch-contour on the accented syllable, for example, H vs. HL in the Colombian language Barasana, [5] accent 1 vs. accent 2 in Swedish and Norwegian, rising vs. falling tone in Serbo-Croatian, and a ...
Switzerland said on Tuesday it was concerned by U.S. President-elect Donald Trump's proposals to raise tariffs and is considering how to respond if his new administration does so. Trump aims to ...
Trills involve the vibration of one of the speech organs. Since trilling is a separate parameter from stricture, the two may be combined. Increasing the stricture of a typical trill results in a trilled fricative. Trilled affricates are also known. Nasal airflow may be added as an independent parameter to any speech sound.
Visible Speech is a system of phonetic symbols developed by British linguist Alexander Melville Bell in 1867 to represent the position of the speech organs in articulating sounds. Bell was known internationally as a teacher of speech and proper elocution and an author of books on the subject.
